Paul English, the co-founder of travel search site Kayak, said his soon-to-launch consumer tech incubator called Blade in Boston’s Fort Point neighborhood will balance innovation and fun. And, also, it may get a little loud after dark.

English, who said Blade will open sometime in April and feature a bevy of as-yet-unnamed startups, said he’s spent thousands of dollars on loudspeakers attached to the ceiling of the space, which is in the basement of 250 Summer St. right up against Fort Point Channel.

"I'm actually designing Blade to run as a startup factory during the day, but it can transform itself almost into a nightclub at night," English told a crowd gathered at a Greater Boston Chamber of Commerce breakfast Tuesday morning. "If you go visit Blade, you'll see it looks like a high-tech office with a lot of the high-tech accoutrements, but if you look up at the ceiling, you'll notice $100,000 worth of speakers. We're going to make sure our parties are when the tenants upstairs are not working."

English said the reason he decided to put a lot of money and energy into the "entertainment side" of the business is to attract people who are focused on consumer-oriented design. "We'd like to do something to create some excitement of bringing together the intersection of art and science and finding a venue that brings together the best designers, the best artists in Boston with some of the best hackers to try to figure out how we can create the next great companies in Boston."

English has said he is raising $20 million for the venture, using the money to make seed investments in the 10 consumer tech companies that will be housed in the 6,000-square-foot space. English said Blade will put between $500,000 and $2 million into each company.

"I'll help them hire the first 10 people, help with the marketing plan, help put together a prototype," said English. "At the right time, I'll help them raise a Series A, kick them out and then we'll go to the next one."

English, who had headed Kayak's engineering office in Concord, had reduced his duties to part-time last year and then left the company, following Kayak's $1.8 billion acquisition by Priceline.
